ROTARY ENGINE.

at Vantrcnt, in the county of` Placer and State of California, have invented certain new and useful Improvements in Rotary Engines, of which the following is a specilication.

'lhe present invention relates to rotary engines and consists in certain parts and combination of parts which will be. hereinafter described and which will be more particularly pointed out in the claims.

The invention is shown in the accompanying drawings, in which,

Figure I is a front view of the improved engine' Fie. II is a longitudinal vertical sec- ZD J D vided with a lower cy tion; Fifi. III is a transverse vertical section; Fig. IV sthows a part of thecasing in perspective viewg' Fig. V is a section on line V-V, Fig. III, some parts being omittted; Fig. VI is a section on line VI-YI, Fig. III, some parts being broken awa-v, and Figs. V II, VIII, and IX show sonic details in perspective. views and on a reduced scale.

The casing of the engine consists ofltwo )arts 1 and 2 mounted on a. base 3 and 'closed by a cover 4. Each )art of the casing isprolindrical recess 5 andan upper semi-cylindrical recess 6 to receive the cylinder-wheel 7 and the abutment-wheel S which have their shafts 9 and 10 journaled in the casing and in a support 11 extending upwardly from the base 3. and 10 are provided with intcrmeshin g gearwheels 12 and 13 which cause the wheels 7 A and S to move 1n unison.

The casing is provided with a longitudinal U-shap'ed recess 14 in which is arranged a correspondingly shaped valve 15 having solid end portions 16 and 17 which are separated by a gap 1S for the cylinder' wheel 7. Near the ends of the recess 14 the easing is provided with horizontal transverse exhaust rnembers having openings 29 and 30.,

cylinder space 5.

I 'l I The vaive 1`5 is mounted toslide in the rel' cess 14 and b v ineans'of a connecting rod 3l and a lever 32 the valve can be shifted to alternately close the exhaust'fchannels and cause the openings `29 and 3() to register with the inlet ports 23fand 24 to establish communication between the inlet-ports and the recess or cylinder' space 5.

rangement of the parts is selected in such a manner' that when the end portion 'i6 closes exhaust 2O is open andthe inlet-port24 is closed. gine. sitions by means of a spring-pressed catch 33 which is adapted to engage in either one of the two notches 34 and 35 of a segment 36.

The cylinder-wheel is provided with a.' pair of semicircular lz'rnges 37 and 3S which are -located on opposite sides of-the wheel both in circi-nnferential direction and in transverse direction. At the place where the flanges meet the wheel 7 is provided with a piston-blade 39 which is arranged in a recess 0in the wheel 7 and is held by a spring 4l against 'the circumference ofthe wall of the The blade 39 is spaced transverse y from the Ranges 37 and 38.

' The abutment-wheel S is rovided with grooves 42. and 13, which are ocated on opposite sides of the wheel and in which engage the flanges 37 and 3S of the cylinder-wheel 7. The wheel S is further provided with a pocket -14 into which the piston-blade 39 is adapted to pass when the wheels rotate in abutment with each other. On theperipheral wall of the cylinder space 5 are secured a pair of rings 45 and 16 which extend a )proxilnately from the inlet-port 23 to the in etort 24, in the direction of the arrow (Fig. II). The rings extend in a radial direction from the peripheral wall of the cylinder space 5 to the periphery of the wheel 7 and are spaced from the side walls of the cylinder-space to permit of the rings entering the s ace between the piston-blade 39 and the anges 37 and 3S during the rotation of the wheel 7.

The operation of the engine is as follows: Let it be assumed that the valve 15 is in the position shown in Fig. III, the end portion 16 closinv the exhaust 19 and the opening 29 registering with the inletport 23. The cylinder wheel 7 .then rotates in the direction of It is thus possible to reverse the en- A T he valve 15 is secured to the two po- @other motive fluir iows into the cylinder "eontaets with the cylinder whee directly be- A, the'arrow (Fig. Ill) and carries along with l .it the abutn'rent wheel S through the medium I A of the gears .12 and 13.

As soon asV 'the piston-blade 39 has passed the inlet-port 23 the flange 3S of the cylinder-wheel 7, which nlp to that moment has kept the inlet-port 23 osed, opens the port 23, and the steam or space between the rings 45, 46 and t-he piston-blade 3f) and the t rtl-surface of the flange 38 reeeive the impact of the steam whereby the cylinder wheel 7 is rotated in the direction of the arrow. As the abutment-wheel hind the inlet-port 23 the steam cannot escape from the c vlinder space in that direction. rl`he inlet-port 123 remains open'until the ejr'l'inder-wheel 7 has rotated 180 wl'ren the flange 3S reaehes the port 23 anal closes the same. From that moment the c vlinderwheel is rotated by the expansion of the steam in the c r-'linder-spaee. W'hen the o vlmiler-wheel has turned about further the piston-blade 39 reaches the exhaust 30 and the steam eseapes therethrough. The rnornenturn of the engine completes the. revolution of the wheels and when the piston-blade reaches the inlet-port 23 the steps of the operation are repeat-ed in the aforesaid manner. During the rot-ation of the wheels the tlanges 37 and 3S engage in the grooves 42 and 43 and the piston blade 39 engages in t-he pocket 44, onee during eaeh revolution of the. wheels.

Then it is desired to reverse the engine the valve 15 is shifted b v means of the lever' 32 to cause theend-portion 17 to close the exhaust 2() and to cause the opening 301-0 register with the inlet-port 24. At the same time the end-portion 16 has moved to the left to open the exhaust 19 and the opening 2S does not any longer register with the. inlet-port 23. In this instance the steam passes from the inletport 24 to the exhaust 19, rot-ating the cylinder-wl'reel in the opposite direction of the arrow (Fig. III) and the flange 32' of the cylinder wheel 7 alternately opens and closes the inlet-port 24.

Itis obvious that more than one pistonblade may be used in which ease a. corresponding number of pockets must he pro- I clairrrand desire vided in theabutment-wheel andthe locatron of the exhausts must then be changed.

Having thus described my invention, what ent is:

1. In a rotary engine, a. easing provided with an inlet-port andan exhaust-port, a cylinder-wheel arranged in-.the easing and having a radial flange extending over halt the periphery of the wheel and of less thickness than the wheel and adapted to alternately open and close said inlet-port, and an abutment-wheel in peripheral Contact with the cylinder-wheel and having a peripheral groove adapted to receive the flange of the e 'lim lerwlreel.

2. In a rotary engine, a easing provided to s efure b v Letters Patwith inlet-ports and'exhaust-ports, a eylinderwheel arranged in the casing and having a, pair of radial flanges extending over halt the periphery of the wheel and located on oppositesides of the wheel both eireum'terentially and transversely, a piston-blade carried by the cylinder-wheel, an' abutment-wheel having grooves for the. flanges and having a pocket for the piston-blade, -and"fa valve shiftable to alternately open and closrthe exhaust ports and inlet-ports to reverseilthe engine. the flanges ol the cylhitler-wheel ligeingada )tedio keep the inlet-ports closed during halt' the revolution of the cylinder wheel.

3. A cylinder-wheel for' rotary engines pro vided with a radial flange of less thiekness\8\ than the wheel and extending over half the periphergY of t-he wheel.

4. A eylirnler-wheel for rotar engines pro- Avided with a pair ot radial flanges of less thickness than the wheel and each extending over half the periphery of the wheel; said flanges being located on opposite sides of the wheel, both transversely and circumferentially.
